Light source evaluation apparatus, light source evaluation system, light source adjustment system, and method for evaluating a light source

Abstract

Provided are a light source evaluation device, a light source adjustment system, a light source evaluation system, and a light source evaluation method whereby it is possible to evaluate the characteristics of a solar simulator, which is a light source for measuring the characteristics of a solar cell, without creating a reference cell or pseudo cell tailored to the spectral sensitivity of a solar cell to be measured. Said evaluation is performed by calculating an evaluation value of the characteristics of the light emitted by a solar simulator in comparison to natural sunlight on the basis of the spectral irradiance of the light emitted by a solar simulator as measured by a spectroradiometer, the spectral irradiance of natural sunlight, and the pre-measured spectral sensitivity of the solar cell to be measured.

Benefits of technology

[0057]According to the present invention, the evaluation value of the characteristics of the light radiated from the solar simulator corresponding to the natural sunlight is calculated based on the spectroradiometer-measured spectral irradiance of the light radiated from the solar simulator, the spectral irradiance of the natural sunlight, and the previously measured spectral sensitivity of the measuring object solar cell; and thus there are provided a light source evaluation apparatus, a light source evaluation system, a light source adjustment system and a method for evaluating a light source which can evaluate the characteristics of the solar simulator, which is a light source for measuring the characteristics of the sola cell, without making a standard cell or a dummy cell which has a spectral sensitivity similar to that of the measuring object solar cell.

Problems solved by technology

However, in the method of Patent Document 1, when the standard cell (dummy cell) is produced, the thicknesses of the semiconductor layers are intentionally differentiated and the glass filter is laminated in order to reflect the spectral dependency of the component cells; thus it takes a lot of time, effort, and cost to fabricate the standard cell (dummy cell).

These problems are caused by fabricating the standard cell (dummy cell) as hardware.
